This application claims the benefit of U.S. Provisional PatentApplication No. 61/939,005, filed Feb. 12, 2014, the contents of whichare hereby incorporated by reference in its entirety.

FIELD

This invention relates to barriers for rain gutters and similarstructures for keeping leaves and other debris out of the rain gutters.More particularly, this invention relates to rain gutter debrispreclusion barriers, which utilize a conformed screen to allow water topass into the gutter, but preclude debris from passing through thescreen and into the gutter.

BACKGROUND

Prior art gutter debris preclusion devices are known to have difficultyin addressing excessive flow of rainwater coming off the roof of a houseinto the gutter. With excessive water flow, debris often accumulates onthe device, clogging or impeding the effectiveness of the devise. Manycomplicated designs have been contemplated by others in the industry,each with their advantages and disadvantages. Of particular difficulty,is the need to support the “guard” over the gutter, wherein complicatedand diverse support and bridging systems have been devised. Thesesupport systems add to the complexity, weight, and most importantly thecost of these guards. The industry was in need of a new system tosupport the guard over the gutter with easy installation, little or noincreased weight, and without increasing the cost of the guard.

The present invention overcomes the deficiencies in the art by creatingvarious systems and devices of screened gutter debris preclusion.

DETAILED DESCRIPTION

FIG. 1A is a side perspective view 100 of an embodiment of a three piecegutter cover showing a rear strip connector 115 that goes to the roof(not shown), a front strip connector 125 that fastens to the front lipof a gutter (not shown) and a corrugated mesh 135 that spans between therear strip connector 115 and the front strip connector 125, via trough145. The mesh 135 in this embodiment is formed of a stainless steelmaterial, but other weather resilient materials may be used. The mesh135 is generally rectangular in shape having a longitudinal axisparallel to the gutter, so as to fit over the gutter. Most residentialgutters being approximately 5 inches in width, and commercial guttersbeing up to 10 inches in width, the mesh 135 will be sized in mostembodiments to be wide enough to cover the gutter, less the widths ofthe rear and front strip connectors 115, 125, if they are used.

Illustrated in FIG. 1A are corrugations 112 in the mesh 135, which canbe of varying shapes, orientations, etc., but are of a configurationthat provides sufficient rigidity in the mesh 135, so that it canfree-formingly span the gutter without collapsing in the gutter. Thesecorrugations 112 do not have to be perpendicular to rear strip connector115. The corrugations do not have to be perpendicular to the front stripconnector 125 in other exemplary embodiments.

FIGS. 1B-C are illustrations of various meshes 135 with corrugations 112that are formed with different diameter wires. For example, FIG. 1Bshows a 30 wires per linear inch corrugation 112. FIG. 1C shows a 50wires per linear inch corrugation 112. Of course, other wires per linearinch density (or metric equivalent) can be used, as well as perforationsor other mechanisms for forming passageways in a material. FIGS. 1B-Care demonstrative of exemplary commercial embodiments and are understoodnot to be limiting.

In the various embodiments described herein, the mesh's corrugations 112can be patterned to be rectangular, square, of various shapes, etc., andoriented substantial orthogonal (perpendicular) to the orientation ofthe lip of the gutter. The perpendicular orientation provides for linearor planar stiffness along the roof-to-gutter lip line, resulting in aself-supporting mesh. The mesh's corrugations can be formed fromstamping the mesh, pressing the mesh, or weaving the mesh in acorrugation form, and so forth.

The connectors 115 and 125 are similar to the lower and upper stripsdescribed in published application US 20110056145, published on Mar. 10,2011, which is incorporated herein by reference in its entirety.

The corrugations 112 formed in the mesh 135 are formed similar to thecorrugations formed in the mesh in published application US 20110056145,published on Mar. 10, 2011, which is incorporated herein by reference inits entirety.

The mesh 135 provides the function of allowing water to pass into thegutter wile precluding debris from passing into the gutter. Thiscorrugated mesh 135 is preferably formed as a woven screen of stainlesssteel wire or other wire/thread of suitable material. Importantcharacteristics of the material forming the mesh include sufficientlyhigh strength and inelasticity to function structurally, as well asresistance to corrosion in the gutter environment. Furthermore, it isadvantageous that material forming the corrugated mesh 135 can bereadily bent sufficient to cause the material to be readily corrugatedinto one of a variety of different cross-sections and hold thatconfiguration after being so bent. Most preferably, the wire forming thecorrugated mesh 135 extends in a pattern with some threads extendingparallel with an upper edge (extending substantially parallel to theroof when in use) of the overall corrugated mesh 135 and some of thewire/thread extending perpendicular to the upper edge. In such aconfiguration, the corrugation can occur to create the crests andvalleys with only the threads, which run parallel with the upper edgeneeding to be bent. In such a configuration the corrugating of the finemesh material forming the corrugated mesh 135 can more readily occur andthis material forming the corrugated mesh can more readily maintain thiscorrugated configuration during installation and use.

The corrugations 112 in the corrugated mesh 135 preferably have anamplitude between crests and valleys between one-fourth and one-tenth ofthe length of the corrugated mesh 135 between the upper edge and a loweredge extending substantially parallel to the gutter lip when in use) ofthe mesh 135 and similar to a width of the opening in the gutter.Preferably, the corrugations 112 are in a repeating pattern. Thispattern is most preferably a sinusoidal pattern with a curving crest andcurving valley. Other configurations can also be provided for thecorrugated mesh 135.

It should be apparent that the mesh may be of any material that isweather resistant, has apertures for drainage, and is of sufficientstiffness to bridge the gutter without the need for an auxiliarysupport. Therefore, the gutter cover can be constructed of othermaterials such as plastic, expanded metal, perforated metal, slottedmetal or louvered metal slits, and so forth. Furthermore, the mesh, withits associated corrugations does not need to completely span the gutter.That is, the mesh's corrugations can be limited to certain portions,according to design preference, and may not need span the entirety ofthe gutter. For example, the trough nay be corrugation free. It shouldalso be apparent that the front strip connector and the rear stripconnector can be formed from metal, plastic, or any other suitablematerial.

It is understood that in various other embodiments, the trough 135(shown in the ions embodiments as adjacent to the front strip connectorand parallel to the longitudinal axis), can be angled to the front stripconnector as well as be oriented at an angle to the mesh's corrugations.Therefore, it is understood that mesh corrugation shapes can bemodified, as well as the trough's angles without departing from thespirit and scope of this disclosure. For example, the trough can haverepeating angles, such as a zigzag, or turns, or smooth gradual turnsand so forth, wherein the corrugations may conform to the trough angles.

In addition to assisting in stiffening the mesh, the corrugations mayresult in an non-smooth or uneven mesh surface, which naturally allowscollected debris to dry quicker (due to separation between the debrisand the mesh surface) and blow off more easily when there is ambientwind.

FIG. 2 is a semi-side cut-away illustration 200 of the embodiment ofFIG. 1A. As illustrated, when the mesh 235 connects to the back of theroof 210 and the gutter 220, via strip connectors 215 and 225, a naturaldownward slope in mesh 235 is created toward the front lip 230 of gutter220. The mesh 235 includes a plurality of corrugations 212. Accordingly,when rainwater comes down the roof 210 and on top of mesh 235, therainwater naturally passes through the apertures in mesh 235 and a largeportion thereof clings to the underside of mesh 235 without falling off.The lightweight and adhesive properties of rainwater allow it to clingto the underside of mesh 235, wherein the slope of the mesh 235 causesrainwater to travel towards trough 245. The bottom 265 of trough 245 isdesigned to be lower than the front lip 230 of gutter 220, therebycreating a barrier that deflects the underside rainwater down into thegutter 220. The arrangement of this “creased” structure preventsrainwater from running off the front of the gutter 220.

In various embodiments, it has been discovered that the cross sectional“crease” forming trough 245 also can operate to increase the structuralintegrity of the surface area of the mesh 235 over the gutter 220. It isunderstood for a large spanning mesh 235, the placement of trough 245 inthe middle of mesh 235 may lessen its ability to independently supportmesh 235. For example, if the mesh 235 is composed of a steel meshhaving a wire diameter that is less than 0.01″ thick, with a weave countof more than 32 wires per linear inch (See FIGS. 1B-C, for example),then placement of the trough 245 in the middle of mesh 235 will beinsufficient to adequately stiffen the gutter spanning mesh 235 to beself-supporting over gutter 220.

If the wire diameter decreases, then the wire count per inchincreases—this will make the mesh 235 less stiff and unable to sustainitself over a gutter 220 when a cross sectional crease (e.g., trough 245or similar trough) is formed. For wire diameters that are between 0.009″and 0.01″ (thicker wire applied to the lessor wire count per inch), withwire counts of 32 to 60 per inch, the trough 245 can be displaced fromthe front strip connector 21 by up to 1.5.″

For wire diameters that are between 0.007″ and 0.089,″ with re counts of36 to 56 per inch, the trough 245 can be placed up to 0.75″ from thefront strip connector 225. For wire diameters that are between 0.005″and 0.069,″ with wire counts of 40 to 50 per inch, the trough 245 can beplaced up to 0.25″ from the front strip connector 225.

However, the trough 245 could be formed on the mesh 235 between the rearand front strip connectors (215 and 225) on a standard 5 inch gutter topopening, if the wire diameter is between 0.011″ and 0.015″ and the wirecount is between 20 and 31 per inch. If a lower wire count per inch ofbetween 10 and 19 is needed, then the wire diameter would need to bebetween 0.016″ and 0.02.″ However, with the wider mesh hole openings, asin the latter example, pine needles and small leafy debris may penetrateinto the mesh 235 and into the gutter 220, potentially clogging thegutter 220 to cause rainwater to spill out of the gutter 220.Accordingly, while a lower wire count per inch for mesh 235, such as 20wires per inch or less, can be used, it will be less effective in debrispreclusion.

Having the mesh-clinging rainwater drop in to the middle of the gutter220 rather than near the front lip 230 of the gutter 220 reduces thepossibility that rainwater will run out of the gutter 220. However,because a higher wire count per inch functions to keep out leaves, pineneedles and roof sand grit, etc. from entering the gutter 220, the mesh235 will be stiffer and accordingly trough 245 can be close to oradjacent to the front strip connector 225.

The trough 245 can be, for example, V-shaped to provide stability,strength and rigidity for supporting the back bend 246 of the trough245, as shown in FIG. 2 where the trough 245 is adjacent to the frontstep connector 225. The front strip connector 225 can act as additionalsupport for the trough 245 when adjacent to each other. It is importantfor the bend 246 along the length of the mesh 235 (nearly adjacent tothe front strip connector 225) to be sufficiently rigid so as to sustainthe span of the mesh 235 to rear strip connector 215. Another reason forthe needed strength and support along bend 246 is if the mesh 235 everbecomes weighted down with leaves, pine needles, roof sand grit or snowand ice. The added strength prevents or reduces the possibility of themesh 235 collapsing into the gutter 220.

The corrugations 212 on the mesh 235 of this embodiment 200, include atleast one corrugation 213 that extends from an upper edge of the mesh235 (near connector 215) into a portion of the trough 245. Thecorrugation 213 does not extend all the way through the through 245 tothe lower edge of the mesh 235 (near connector 225). The corrugations212 further include at least one corrugation 214 that extends from thelower edge of the mesh 235 through the trough 245. The corrugation 214in this embodiment does not extend all the across the surface of themesh 235 to the upper edge. In other exemplary embodiments, thecorrugations do not extend into the trough.

As shown in the cross-sectional illustration of FIG. 3A, the trough 345can be composed of multiple troughs, the additional trough 375 appearingalong the lower side of the mesh 335. The rationale for additionaltroughs is to provide more barriers, which act to divert higher flows ofrainwater into the gutter 320. It is understood that higher flows ofrainfall could potentially pass through a single barrier, which canarise from severe weather storms or from larger surface areas of a houseroof where rainwater has accumulated in a roof valley and channeled tothe inside corner of a covered gutter. It is understood that the mesh335 that is running adjacent to the front strip connector 325 can beformed into a variety of different shapes. It is further understood thatthe mesh 335 includes corrugations, not shown, that extend at leastpartially through the trough 375.

FIG. 3B is a cross-sectional, close up illustration of an exemplarytrough 375, with V-shape formed from three bends 381, 383, and 385; andis illustrative of how rainwater typically travels along the mesh 335into the trough 375. Rainwater generally will travel under the mesh 335and when encountering the barrier forming side/surface H of the V-shapedtrough 375, travels down and eventually drops off from the end. E ofbend 383, which forms the low point of trough 375, in some instances,rainwater will flow on the top of mesh 335 and flowing over bend 385encounter side/surface G, which diverts the water into the bottom oftrough 375. The entering water will drain through the apertures insurfaces H and G, into the gutter (not shown).

Understanding that additional and/or varied shaped troughs can also beformed, FIG. 4 is an illustration 400 of mesh 435 with trough 445 formedwith a plurality of upward protruding barriers 475 and 485. In someembodiments, combinations of the troughs shown in FIGS. 2 and 3A may beutilized, as well as other shaped troughs. Accordingly, trough 445 canbe an inverted V, U, laterally oriented L, or laterally oriented relaxedL shape, for example. It is further understood that the mesh 435includes corrugations, not shown, that extend at least partially throughthe trough 445.

FIGS. 5A-B are illustrations of n embodiment of a mesh 535 with aU-shaped trough 545, described here as having four bends 581, 583, 584and 585. The principal rainwater barrier is formed by surface H, whichforces under-mesh traveling water towards bends 583 and 584, which formsthe lowest points of trough 545. The ensuing water can penetrate throughsurface H into drain through to neighboring surface G, or be diverted bysurface H down towards bends 583 and 584, and fall into the gutter 520.It is further understood that the mesh 535 includes corrugations, notshown, that extend at least partially through the trough 545.

It should be apparent that the V-shaped troughs in FIGS. 2-4 and theU-shaped trough(s) in FIGS. 5A-B only require a minimum of three bendsin the mesh for the V-shape and four bends for the U-shape to form theirshapes. The wall barrier formed by surface H in FIG. 5B has a uniquefeature in that if it is formed anywhere in the open surface area ofmesh 535, even along the longitudinal midline axis of the gutter (e.g.,further away from the front strip connector 525), the mesh 535 willretain a significant amount of its rigidity. Therefore, mesh 535 will beless likely to collapse in the gutter 520 from the weight of leaves,pine needles, roof sand grit or snow and ice. This “supportability” isdue to the fact that when downward pressure is applied to either sidesof mesh 535, from debris, etc., bends 581 and 585 will push against eachother to stiffen against further downward movement in mesh 535.

FIG. 6A is a side-view illustration of a mesh 635 embodiment with alaterally oriented L-shaped trough 645. The mesh 635 covers gutter 620and is attached to the gutter's front and rear ends via rear stripconnector 615 and front strip connector 625. The void formed by thetrough 645 operates to provide a debris collection area 655. It isfurther understood that the mesh 635 includes corrugations 610 thatextend at least partially through the trough 645. It is furtherunderstood that the mesh 635 includes corrugations, not shown, thatextend at least partially through the trough 645.

FIG. 6B is a close-up illustration of laterally oriented L-shaped trough645, showing only two bends 681 and 683 in mesh 635, to form the trough645. Two bends 681 and 683 create a firmer support structure of thesurface area of the mesh 635 than with three displaced beads, theexception perhaps being the embodiment of FIGS. 5A-B, where the threebends are in close proximity to each other. Under-mesh 645 travelingrainwater will travel to bend 683, which forms the lowest point of mesh645, and drop into the gutter 620. Surface G operates as a dam againstonrushing water and a collection area for debris, allowing accumulatingwater to drain through the respective apertures in the mesh 645.

FIG. 7 is an illustration of the embodiment of FIG. 6A in a snowmeltsituation. Snow 705 accumulating on the roof shingles/surface 710 willmelt to form snowmelt 707 over mesh 735 traveling towards the trough745, which is connected to front strip connector 725. Water melting fromsnowmelt 707 penetrates the mesh 735 and travels under the mesh 735 totrough 745. The lowest point of the trough 745 (bend 683 in FIG. 6B)acts as the drip point, causing the water to drop 709 into the gutter720. It is further understood that the mesh 735 includes corrugations710 that extend at least partially through the trough 745. It is furtherunderstood that the mesh 735 includes corrugations, not shown, thatextend at least partially through the trough 745.

FIGS. 8A-B are illustrations of another embodiment wherein the trough845 has a laterally oriented relaxed. L-shape for accommodating debris,shown here as the debris collection area 855. FIG. 8A illustrates themesh 835 attached to the gutter/roof via strip connectors 815 and 825.Trough 845 is disposed in the mesh 835 proximal to the front stripconnector 825, which is attached to the gutter 820. The trough 845 isformed from two bends 881 and 883 in the mesh 845, however, the surfaceG between the two bends 881 and 883 is less vertical than in theembodiments shown in FIGS. 6A-B. The “less than vertical” orientationresults in a “softer” as steep of a slope for the barrier or surface Gto accumulated debris in the trough 845. That is, since the surface G issloped, the debris will likely blow off of the gutter cover more easilythan in the embodiment shown in FIGS. 6A-B. It is further understoodthat the mesh 835 includes corrugations 810 that extend at leastpartially through the trough 845. It is further understood that the mesh835 includes corrugations, not shown, that extend at least partiallythrough the trough 845.

FIG. 9 is an illustration of the embodiments of FIGS. 8A-B in a snowmeltsituation. Snow 905 accumulating on the roof shingles/surface 910 willmelt to form snowmelt 907 over mesh 935 traveling towards the trough945, which is connected to front strip connector 925. Water melting fromsnowmelt 907 penetrates the mesh 935 and travels under the mesh 935 totrough 945. The lowest point of the trough 945 (bend 883 in FIG. 7B)acts as the drip point, causing the water to drop 909 into the gutter920. It is further understood that the mesh 935 includes corrugations,not shown, that extend at least partially through the trough 945.

Both trough designs shown in FIGS. 8 and 9 provide a feature thatsignificantly reduces potential snowmelt runoff over the gutter coverand unto the ground. To fully appreciate the snowmelt feature, anunderstanding of the snowmelt runoff problem is necessary. When apermeable mesh type gutter cover material is not exposed to rain orsnow, but there is snow on top of the roof, when the snow begins to meltit can drip off the edge of the gutter cover and the gutter. Thisproblem is mainly seen in the micro-mesh type gutter covers with holeopenings less than 0.125″ square.

The reason the snowmelt exits over the side of a mesh gutter cover isbecause the mesh is not wet since there is no rain. Moreover, it ispossible the mesh is frozen, preventing penetration of the snowmelt intothe mesh. In either instance, the snowmelt coming down the roof tends tonot penetrate the permeable mesh material and consequently runs alongthe top of the mesh and then over the front of the gutter. It should beunderstood that snowmelt can occur in below freezing weather, whereinthe roof under the snow is warmed by the home's heat, causing thesnowmelt.

In contrast, when it is raining (which means the temperature is abovefreezing), snowmelt will come off the roof and with the mesh wet fromthe rain, the snowmelt will drop through the mesh and into the gutter.The warming rain droplets striking any snowmelt on the mesh will alsohelp force the snowmelt through the mesh.

Because of the snowmelt issue, the downward trough designs illustratedin FIGS. 7 and 9 incorporate the barrier formed by surface G, whichprovides a permeable mesh wall that the melted snow can penetratethrough. Typically, when snowmelt travels down the roof and onto themesh of FIGS. 7 and 9, it can travel between 3 and 10 miles per hour,depending on the steepness angle of the roof. When the snowmelt hits thesurface G, its momentum can force the snowmelt through the apertures ofsurface G and drop down into the gutter. When the debris collection area655, 855 has no debris sitting in it, the functionality and purpose ofthe downward sides of surface G are greatly enhanced.

FIGS. 10A-B are illustrations of another gutter cover embodiment,wherein either one or more or the front and rear strip connectors is notutilized. For example, the front of mesh 1035, having trough 1045, canbe fastened to the front lip 1027 of the gutter 1020 and the rear of themesh 1035 can be laid on the back lip of the gutter 1020, without theneed of fastening it to any strip connector. In this scenario, the frontlip 1027 of the gutter 1020 acts like a front connector support to holdup the surface area of the mesh 1035 when a screw (not shown) isfastened through the top end portion 1037 of the mesh 1035 and throughthe gutter's top ridge 1029. The screw can be placed through any sectionof the top ridge 1029, however, typically is fastened along thedimensional line 1040. To further create additional support, the mesh1035 can be folded into a flap 1039, which provides additional strengthon the mesh 1035 screwed to the gutter 1020. It is further understoodthat the mesh 1035 includes corrugations, not shown, that extend atleast partially through the trough 1045.

While FIG. 10B shows a single fold, additional folds can be implementedfor greater strength and support. In this embodiment, the trough 1045 isadjacent to the front lip 1027 of the gutter 1020. As stated earlier, invarious other embodiments, the trough 1045 may be disposed at anarbitrary distance from the front of the gutter 1020.

Also, in various embodiments, the trough(s) shown may be composed of themesh material with or without corrugations. That is, one or more of thetrough surfaces H and/or G (seen in FIG. 3A or 5B) may benon-corrugated. For example, the mesh “corrugations” could begin fromthe rear strip connector and continue to the second bend in the trough,or stop at the first bend and resume from the second bend. In otherembodiments, as seen in FIGS. 6B and 8B, because there is sufficientstrength in the mesh on the surface H, due to being supported by thefront strip connector, the mesh corrugations could go from the rearstrip connector and stop at the second bend. It should be understoodthat the term corrugation can be interpreted as a structure thatprovides apertures for drainage, such as a perforation, slot, slit,overlaying wires with gaps, and so forth in the respective gutter cover.

FIG. 11 is a semi-side cut-away illustration 1100 of the embodiment ofFIG. 1A. As illustrated, when the mesh 1135 connects to the back of theroof 1110 and the gutter 1120, via strip connectors 1115 and 1125, anatural downward slope in mesh 1135 is created toward the front lip 1130of gutter 1120. This embodiment is similar to the embodiment of FIG. 2,in that it includes a trough 1145 having surfaces G and H, along withthe end point E. The device 1100 also has corrugation 1113, whichextends into the trough 245 and corrugation 1114, which does not extendall the way to the top end of the mesh near connector 1115. A differencewith the present embodiment is that the corrugations 1112 extend in anon-perpendicular direction relative to the gutter lip 1130. Whereas inthe embodiment shown in FIG. 2, the corrugations are substantiallyperpendicular to the gutter lip. It should be appreciated that in otherexemplary embodiments, the corrugations extend along the mesh in avariety of manners. Still further, in other embodiments, thecorrugations extend along the mesh in differing angles relative to thegutter lip or the strip connector.
